Flashcards in Codes & Regulations During Programming Deck (61)
What 4 things can states do with IBC?
1. Adopt all or just some chapters
2. Adopt current or earlier version
3. Adopt all / some / none of complementary codes
4. Can include additional requirements or modify sections
American with Disabilities Act (ADA)
Federal level law that regulates removal of barriers to physically disabled.
-requirements based on ANSI A1117.1
In addition to state building code (typically a version of IBC), what other codes can state govt enforce?
1. Energy codes
2. Elevator construction requirements
3. Environmental regulations
4. Rules related to state govt bldgs
5. Fabric flammability standards
What is a type of local regulation?
What types of amendments can local codes make to model building code in use?
Amendments that pertain to specific needs of a geographic region, or provisions designed to alleviate local problems not addressed in model codes.
Ex: mountainous area may require higher snow-load factor for roof design bc of local climate
Whose responsibility is it to enforce codes?
Local building department or AHJ (Authority having jurisdiction)
One that has been written by group of experts knowledgeable in field without reference to specific geographic area
Most commonly used model code
IBC (International Building Code)
What’s it mean that IBC is prescriptive based?
Describes specific materials / methods of design to be used rather than how components are supposed to function
Least acceptable risk
Minimum level needed for building & occupant safety
Agency that writes standards and test procedures that prescribe how test apparatus must be set up, how materials must be prepared, and how long test must last
National Fire Protection Association
-private, voluntary organization that develops standards related to cause and prevention of destructive fires
What does ANSI do?
Approves standards developed by other organizations
Signifies product has passed safety test & is manufactured under UL follow-up services program. When a product is successfully tested it’s listed
Samples of a product were tested for certain types of uses only. Must specify conditions that were tested for.
National Recognized Testing Laboratory
Best known NRTL; when a product passes test, it’s given a UL label.
What is most common use of UL procedures?
Testing doors & other kinds of protection for openings.
How does building code tie into testing materials?
Building code indicates what tests / standards a material must satisfy to be acceptable for use
What are product tests concerned with the most?
What do fire safety tests rate?
How well a construction assembly can keep fire/smoke from passing from one space to another & rate flammability of finish material
What 3 tests are commonly used to rate fire resistance of construction assemblies?
1. ASTM E119 (Standard test methods for fire tests of building construction and materials)
2. NFPA 252 (Standard methods of fire tests for door assemblies)
3. NFPA 257 (standard on fire test for window & glassblock assemblies)
Describe ASTM E119
1. Heat transfer through assembly is measured to see how long fire must be applied to one side of the assembly before the other side combusts
2. Hose stream test - duplicate of assembly is exposed to fire for half the time determined by first part of test. Then a steam of high pressurized water is directed at assembly to test assembly’s integrity & to withstand impacts.
What time ratings are given to materials tested according to ASTM E119?
1-hour, 2-hour, 3-hour or 4-hour
Describe NFPA 252
Evaluates how well a door or opening assembly resists passage of flame, heat, gas. 2-part test:
1. Establish fire endurance rating
2. Hose stream test (will determine if door will stay in frame when subject to blast from fire hose after exposure to fire).
Describe NFPA 257
Gives specific fire and hose stream test procedures to use to establish degree of fire protection (in units of time) for window openings in fire resistive walls. Determines degree of protection from spread of fire, including flame, heat & hot gases.
What do flammability tests determine?
1. If material is flammable & if it burns with applied heat or supports combustion
2. Material is given flame spread index (FSI) from 0 to 100
3. Materials classified into 3 groups based on flame spread.
List FSI ratings from most fire resistant to least
Class A (I) - FSI = 0-25
Class B (II) - FSI = 26-75
Class C (III) - FSI = 76-100
List 3 common flammability tests
1. ASTM E84
2. NFPA 265
3. NFPA 286
